I don't have the clamping elements but am considering getting some. My workbench has 3/4" dog holes. How snug are the clamping elements in the 20mm MFT holes? Will I have to open up my dog holes a little or is there any play in the 20mm holes? Also, do you think they provide enough clamping pressure for glue-ups as you stated in your video?

The clamping elements are pretty snug in the 20mm holes. I sincererely doubt you could use them in a 3/4" hole without opening up the hole a bit, or sanding down the clamping element post.

They're up to the task of doing a panel glue up: e.g. cutting boards, the panel for a door, etc. I would not rely solely on them. They will provide a good holding action while you apply cauls, and more clamps (unless you have a bunch of clamping elements).

In terms of gluing up of thicker stock (e.g. leg glue ups, laminations for large turnings, etc) you are better off gluing in a horizontal position and using clamps for putting pressure towards the workbench, rather than laterally as the clamping elements do. But, that's not to say it wouldn't work-- you could use the clamping elements supplemented by more regular clamps to provide distributed pressure.

Nice job junkie. The one thing you didn't mention in your video is that the F style clamps can also be inserted from below the table in the event you don't want the body of the clamp above the table. Also, the screw type clamps are sold in pairs and the quick clamp is sold individually. I know I'm nit picking, sorry.
